Description	The article deals with an omnidirectional multi-lobe passive direction finder (PDF) that uses the modified Butler matrix operation algorithm and a digital amplitude direction finding method for the direction of arrival determination of the signal of interest. The article brings a concept of the PDF with the multi-lobe circular antenna array (CAA) for the omnidirectional interception of signals and results of the DOA determination obtained with the experimental CAA. These practical results of measuring with experimental CAA are compared with the theoretical results obtained by means of mathematical models of the PDF based on an approximation of real antenna patterns. To approximate the real antenna pattern of CAA antenna elements, an appropriate form of the Gaussian curve is used.
